An upgraded version of the Graze's prototype, the Schwalbe Graze is a trial machine born during the Graze's development process with the goal of achieving both high output and high mobility. Gjallarhorn once planned to deploy the Schwalbe Graze as its main machine, but this was dropped due to the mobile suit's operational and high development cost. The Schwalbe Graze thus lost to the lower cost Graze in the competition to be Gjallarhorn's main machine, even though both units use the same frame. As such, very few units were produced, making Schwalbe Graze a rare machine. However, it was recognized as a commander-type machine and deployed as such.
